The Monticello – Growers Edition is the ideal greenhouse designed for crops that require a lot of light in a private and secure setting.  The Monticello is constructed from the highest quality extruded aluminum (US grade - not the thinner & more brittle foreign aluminum) and electrostatically painted Black (guaranteed to contain 0.0% lead). Proudly made in the USA.

Our commercial electric exhaust fan system with built in louvers and commercial thermostat are all made in the USA and help control the temperature inside of your Monticello Greenhouse.

The Growers Edition is standard with our 8mm twin wall roof and wall panels that are light diffusing, creating a glow rather than a beam for more even distribution for longer periods of time.  The light diffusing panels also offer a higher level of privacy, just 8 inches away you cannot see into the greenhouse.    

Other features included in this package are a folding work bench system, a drip irrigation system (customized up to 48 dripper heads) with programmable timer, an electric ventilation system, a 17,000 BTU commercial heater with built in thermostat, and dual automatic roof vent openers.  

The Monticello Growers Edition is still constructed from the highest quality extruded aluminum and professional grade 8mm polycarbonate panels, making it comparable to commercial grade greenhouses. It is also backed by the strongest warranty in the industry (15 years). 

The twin wall polycarbonate acts as a double pain window, keeping cool air in during the warmer months and insulating the greenhouse from cold air in the winter months. This makes the Monticello an ideal greenhouse for gardeners who want to grow year round. 

The above average height (7ft 6") gives you plenty of space to grow taller plants and also helps with displacing heat.

The Monticello is a practical option with the durability of a commercial grade greenhouse, you definitely get what you pay for!

    What is Affirm?

    Affirm is a financing alternative to credit cards and other credit-payment products. Affirm offers instant financing for online purchases to be paid in fixed monthly installments over 3, 6, or 12 months.

    Why buy with Affirm?

    • Buy and receive your purchase right away, and pay for it over several months. This payment option allows you to split the price of your purchase into fixed payment amounts that fit your monthly budget.
    • If Affirm approves your loan, you'll see your loan terms before you make your purchase. See exactly how much you owe each month, the number of payments you must make, and the total amount of interest you'll pay over the course of the loan. There are no hidden fees.
    • The application process is secure and real-time. Affirm asks you for a few pieces of information. After you provide this information, Affirm notifies you of the loan amount that you're approved for, the interest rate, and the number of months that you have to pay off your loan -- all within seconds.
    • You don't need a credit card to make a purchase. Affirm lends to the merchant directly on your behalf.
    • You may be eligible for Affirm financing even if you don't have an extensive credit history. Affirm bases its loan decision not only on your credit score, but also on several other data points about you. 
    • Affirm reminds you by email and SMS before your upcoming payment is due. Enable Autopay to schedule automatic monthly payments on your loan.

    What is required to have an Affirm account?

    To sign up for Affirm, you must:

    • Be 18 years or older (19 years or older in Alabama or if you're a ward of the state in Nebraska).
    • Not be a resident of Iowa (IA) or West Virginia (WV).
    • Provide a valid U.S. or APO/FPO/DPO home address.
    • Provide a valid U.S. mobile or VoIP number and agree to receive SMS text messages. The phone account must be registered in your name.
    • Provide your full name, email address, date of birth, and the last 4 digits of your social security number to help us verify your identity.

    How does Affirm work?

    1. At checkout, choose Pay with Affirm.
    2. Affirm prompts you to enter a few pieces of information: Name, email, mobile phone number, date of birth, and the last four digits of your social security number. This information must be consistent and your own. 
    3. To ensure that you're the person making the purchase, Affirm sends a text message to your cell phone with a unique authorization code.
    4. Enter the authorization code into the application form. Within a few seconds, Affirm notifies you of the loan amount you're approved for, the interest rate, and the number of months you have to pay off your loan. You have the option to pay off your loan over three, six, or twelve months. Affirm states the amount of your fixed, monthly payments and the total amount of interest you'll pay over the course of the loan.
    5. To accept Affirm's financing offer, click Confirm Loan and you're done.   

    After your purchase, you'll receive monthly email and SMS reminders about your upcoming payments. You can also set up autopay to avoid missing a payment.  Your first monthly payment is due 30 days from the date that we (the merchant) processes your order.

    How does Affirm approve borrowers for loans?

    • Affirm asks for a few pieces of personal information: Name, email address, mobile phone number, date of birth, and the last four digits of your social security number. 
    • Affirm verifies your identity with this information and makes an instant loan decision. 
    • Affirm bases its loan decision not only on your credit score, but also on several other data points.  This means that you may be able to obtain financing from Affirm even if don't have an extensive credit history.

    Does Affirm perform a credit check? Does it impact my credit score?

    Although Affirm performs a credit check when you apply for a loan, this won't impact your credit score. However, if you're approved and decide to buy with Affirm, your loan and payments may affect your credit score.  Paying on time can help you build a positive credit history. 

    Why was I denied financing by Affirm?

    The merchant has no information regarding a customer's financing denial. Affirm strives to offer all credit-worthy applicants financing with Affirm, but isn't able to offer credit in every case. Affirm will send you an email with more details about its decision. Unfortunately Affirm's decision is final.

    Why was I asked to verify my identity?

    If Affirm has difficulty confirming your identity, you may need to provide more information. Affirm uses modern technology to confirm your identity, including verifying your address or full SSN, or requesting a photo of your ID. Affirm takes these steps in some cases to counter fraud and provide the most accurate credit decision they can.

    Why was I prompted to enter my income?

    Affirm may sometimes need more information about your finances and your ability to repay in order to make a credit decision. Your income gives Affirm additional insight into your ability to repay.

    Why was I prompted for my checking account?

    Affirm may sometimes need more information about your finances and your ability to repay in order to make a credit decision. If you are prompted to link your checking account and would like to proceed, please provide the login information for your online bank account. Affirm does not store your online login credentials---they are transmitted securely to your bank.

    If Affirm asks you to link your checking account, Affirm won't be able to offer you credit if:

    • Your bank is not listed
    • You choose not to link your checking account
      You don't use online banking
      The username and / or password you provide is incorrect
      *You're unable to successfully connect your checking account

    Why is my bank not listed?

    Although Affirm is continually adding support for additional banks, they aren't able to connect to every bank at the present time. We apologize for the inconvenience. If you're unable to connect your bank, you'll need to complete your purchase with another payment method.

    Why was I prompted for a down payment?

    Affirm isn't always able to offer credit for the full amount you request. In these cases, Affirm asks you to make a down payment with a debit card for the remainder of your purchase. The down payment amount can't be changed and must be made upon confirming your loan and before the loan offer expires.

    Will I see how much interest I am paying prior to accepting my loan?

    Yes! Affirm works hard to be completely transparent. You'll see the amount of interest you'll owe on the terms page and again on the loan confirmation page. If you pay off your loan early, you'll receive a rebate for any interest that hasn't yet accrued.

    Why can't customers outside the U.S. use Affirm?

    Affirm is available only to shoppers residing in the United States. Affirm hopes to expand its services to customers outside the U.S. in the future.

    What are Affirm's fees?

    The annual percentage rate (APR) on an Affirm loan ranges from 10% to 30%. Affirm discloses any required fees upfront before you make a purchase, so you know exactly what you will pay for your financing. Affirm does not charge any hidden fees, including annual fees.  

    Why is my Affirm interest rate so high?

    When Affirm determines your annual percentage rate (APR), it evaluates a number of factors, including your credit score and other data about you. If you finance future purchases with Affirm, you may be eligible for a lower APR depending on your financial situation at the time of purchase.

    This APR calculator will give you an idea of how much interest you actually pay:

    When you consider Affirm financing, carefully evaluate the loan terms that Affirm offers you and determine whether the monthly payments fit your budget.  

    How is interest on an Affirm loan calculated?

    Affirm calculates the annual percentage rate (APR) of a loan using simple interest, which equals the rate multiplied by the loan amount and by the number of months the loan is outstanding. 

    This model differs from compound interest, in which the interest expense is calculated on the loan amount and the accumulated interest on the loan from previous periods. Think about compound interest as "interest on interest," which can increase the loan amount. Credit cards, for example, use compound interest to calculate the interest expense on outstanding credit card debt.

    Waiting on a part

    So far I’m thinking I’ve got a great greenhouse. Very attractive and once I get plants in for the winter, I’ll be a better judge. I was missing a part-through no fault of riverstone— and asked them to ship me 2, and received 1. I haven’t heard back yet
    Whoever can put this together in 2 days with 2 people must be a genius !

    Debi Jaynes
    Still putting this togethrr

    ThIs will be a lovely greenhouse ! I had a concrete slab already there and the men are putting it out so they just can grab and build

    Thank you for the five star review Debi! We really appreciate it so much and can't wait to see what you do with your beautiful orchids in this greenhouse. Happy growing!

    Not up and going.

    It has taken quite a while to go through all the boxes. Some parts are labeled, some are not. Several smaller items were missing. I emailed that and most of it was resent quickly. However, I did not get everything yet and received some extra parts that are not needed.... at least I didn't reorder them. hard to know until we actually get it all and can put it together!

    I am writing about my Riverstone GreenHouse. It is amazing! I dont know which feature I appreciate more! I think it would be the self watering system, which worked excellent! It saved so much time not having to water by hand. Here in western NY we have a lot of strong winds, and it seemed more than normal this past winter. I have to admit I was very anxious several times when the gusts were over 70mph, expecting damage...But am thrilled to say my greenhouse withstood everything mother nature threw at her and then some. It is so well made . My grandchildren, my friend, and myself all had such good time growing seeds into plants and then trying to figure out what we were going to do with all the bounty! Some of the nights were down into the 20s and the young seedlings were ok the next day..very impressive. My greenhouse even looks great! I love your product, and the support team behind it and I would not hesitate to recommend it . Thank you so much for this wonderful gift.

    Dick S. Valatie, NY

    The greenhouse went together very well, with excellent instructions and quality materials. My wife is very pleased with it. This is her second greenhouse so she knew what she wanted in one.
